Description

Technical Field

[0001] This utility model relates to the field of air conditioner defrosting technology, and more specifically, to an air conditioner defroster. Background Technology

[0002] During vehicle use, windshield fogging may occasionally occur due to environmental changes, which can impair the driver's visibility. Severe fogging can prevent visibility of road conditions, potentially leading to accidents. Fogging on the outside of the car is usually caused by lower outside air temperatures, especially in rainy, foggy, or early morning conditions, where humid air condenses on the cold exterior of the window. While fog on the outside can be removed by wipers, fogging on the inside of the window typically occurs because humid air inside the car condenses into water droplets on the cold interior surface, which cannot be removed by wipers. Therefore, an air conditioning defroster is essential.

[0003] Air conditioner defrosters typically have internal and external circulation modes. When switching between internal and external circulation, the baffle swings back and forth. The existing fixing of the baffle is prone to loosening, which affects the switching effect of the baffle. Utility Model Content

[0035] Combination Figure 1-7 As shown, this embodiment provides an air conditioning defroster based on the basic structure of a bus air conditioner. Most bus air conditioners are roof-mounted and located at the top center of the bus. The airflow from the bus air conditioner cannot reach the windshield. A new type of defroster is designed and added. The defroster is connected to the roof-mounted air conditioner and can be switched on and off independently. An air outlet is added to the defroster device to blow air onto the glass for defrosting, thus enabling defrosting of the windshield.

[0036] The air conditioner defroster includes an evaporator 6 and a housing, with the evaporator 6 housed within the housing. Hot and cold water enter and exit the evaporator 6 for heat exchange. The evaporator is a single-piece tube-plate type with 7 rows and 9 holes. The upper 3 rows and 9 holes are for hot water flow, connecting to the car's radiator to enhance heating performance. The lower 4 rows and 9 holes are for refrigerant flow, connecting to the top air conditioner inlet and outlet pipes.

[0037] At least one air outlet is provided on the upper housing of the evaporator 6. In this embodiment, the air outlet includes a first air outlet 11 and a second air outlet 12. Both the first air outlet 11 and the second air outlet 12 are connected to a fan 7. Driven by the fan 7, air is blown from the first air outlet 11 and the second air outlet 12 for defrosting. For example, the first air outlet 11 and the second air outlet 12 blow air towards the windshield to defrost it.

[0038] In other embodiments, a third air outlet 13 and a fourth air outlet 14 may be added to the air outlet. For example, the third air outlet 13 and the fourth air outlet 14 may blow air towards the left and right rearview mirrors respectively to defrost the left and right rearview mirrors.

[0039] In this embodiment, a circulation switching component is provided on the lower side of the evaporator 6. The circulation switching component includes a swingable baffle 2 and connecting blocks 4 disposed at both ends of the baffle 2. Specifically, one side of the baffle 2 has a bent connecting plate 22, and the connecting block 4 includes a lower connecting block 42 and an upper connecting block 43, which are clamped on both sides of the connecting plate 22.

[0040] In this design, the baffle 2 is connected to blocks 4 at both ends. Each connecting block 4 includes a lower connecting block 42 and an upper connecting block 43. The baffle 2 has a bent connecting plate 22, which is clamped between the lower connecting block 42 and the upper connecting block 43. The baffle 2 and connecting block 4 are fixedly connected through a mutual limiting fit between the connecting block 4 and the connecting plate 22, thus limiting and fixing the baffle 2 in its swing direction. Furthermore, the connecting block 4 is also mounted on the housing, allowing it to further limit and fix the baffle 2 at both ends. Compared to the conventional method where the baffle 2 is connected to the connecting block 4 by bolts, which is prone to loosening over time and affecting the switching effect of the baffle 2, this design offers a more efficient solution.

[0041] Combination Figure 3 , Figure 5 and Figure 7 As shown, a limiting cavity 41 is provided between the lower connecting block 42 and the upper connecting block 43, and the connecting plate 22 is located in the limiting cavity 41.

[0042] Regarding the connecting plate 22, the bent connecting plate 22 is formed by first bending one end of the baffle 2 towards one side of the baffle 2, and then bending it a second time towards the other side of the baffle 2. This results in the connecting plate 22 including a first bent portion and a second bent portion. For example... Figure 7 As shown, in this embodiment, the connecting plate 22 is bent into a V-shape. It should be noted that in other embodiments, the connecting plate 22 can also be bent into other shapes.

[0043] The limiting cavity 41 includes a receiving cavity 411 and connecting cavities 412 located on both sides of the receiving cavity 411. The first bent portion formed by the first bend and the second bent portion formed by the second bend of the connecting plate 22 are respectively located in the connecting cavity 412, wherein the connection between the first bent portion and the second bent portion is located in the receiving cavity 411. In this embodiment, the limiting cavity 41 is provided with the receiving cavity 411 and the connecting cavity 412 for connecting, fixing and limiting different parts of the connecting plate 22, thereby increasing the connection strength between the baffle 2 and the connecting block 4.

[0044] Combination Figure 4and Figure 7 As shown, the baffle 2 also includes a swing plate 21 connected to the connecting plate 22. Normally, the baffle 2 can be integrally formed by sheet metal stamping. The circulation switching assembly also includes an inner circulation plate 5 and an outer circulation plate 8 respectively disposed on both sides of the swing plate 21; when the baffle 2 swings, the swing plate 21 contacts the inner circulation plate 5 or the outer circulation plate 8.

[0045] Specifically, the bottom of the defroster is provided with an inner circulation port 15 and an outer circulation port 16; when the swing plate 21 contacts the inner circulation plate 5, the interior of the defroster is connected to the inner circulation port 15; when the swing plate 21 contacts the outer circulation plate 8, the interior of the defroster is connected to the outer circulation port 16.

[0046] To improve the sealing performance of the baffle 2, foam cotton with a thickness of 0.2-1mm is pasted on both sides of the swing plate 21. When the swing plate 21 swings to contact the inner circulation plate 5 or the outer circulation plate 8, the foam cotton not only improves the contact seal but also has the effects of shock absorption and noise reduction.

[0047] To prevent debris from entering the defroster, filter cotton is installed at both the internal circulation port 15 and the external circulation port 16. See Figure 4 As shown, U-shaped sheet metal grooves are fixedly installed at the inner circulation port 15 and the outer circulation port 16, and the filter cotton is fixedly installed in the sheet metal grooves.

[0048] Both ends of the baffle 2 are provided with connecting blocks 4, but one of the connecting blocks 4 is connected to the rotating shaft 31. See Figure 3 As shown, the rotating shaft 31 is connected to the driving component 3. The driving component 3 is an electrode. The driving component 3 drives the rotating shaft 31 to rotate back and forth, and the rotating shaft 31 drives the connecting block 4 to rotate, thereby causing the baffle 2 to swing. When the rotating shaft 31 is connected to the connecting block 4, a connecting hole adapted to the rotating shaft 31 can be opened on the side of the connecting block 4 near the rotating shaft 31, and one end of the rotating shaft 31 is installed in the connecting hole.

[0049] To avoid relative sliding between the rotating shaft 31 and the connecting block 4, see Figure 6 As shown, the outer peripheral side of the rotating shaft 31 includes a connecting wave section 311 and a flat section 312. The shape of the connecting hole on the connecting block 4 is adapted to the shape of the rotating shaft 31.

[0050] The terms “installation,” “setup,” “equipped with,” and “connection” used herein should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0051] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
